Abstract: A bicycle control apparatus is provided with a controller for controlling an output of an assist motor according to a manual drive force. The controller is configured to selectively set a first control state and a second control state, in which output states of the assist motor with respect to the manual drive force are different from each other. The controller controls the output of the assist motor so that a response speed of the assist motor with respect to changes in the manual drive force in the first control state will be faster than the response speed of the assist motor with respect to changes in the manual drive force in the second control state, when a crank of a bicycle is rotated from a stopped state and/or when a rotational speed of the crank is less than or equal to a prescribed first speed.

Abstract: An electrical device for a system of a human-powered vehicle comprises a controller. The controller is configured to selectively act, based on reference information relating to the system, as each of a master controller and a slave controller. The master controller is configured to transmit a first control signal to a different slave controller of a different electrical device of the system. The different slave controller is configured to be operated in response to the first control signal. The slave controller is configured to be operated in response to a second control signal transmitted from a different master controller of a different electrical device of the system.

Abstract: A human-powered vehicle control device for a human-powered vehicle comprises an electronic controller. The electronic controller is configured to control a motor, which applies a propulsion force to the human-powered vehicle, in accordance with a human driving force input to the human-powered vehicle. The electronic controller is configured to control the motor to change at least one of a maximum value of an output of the motor, a first changing ratio of an increase rate of the output of the motor to an increase rate of the human driving force, and a second changing ratio of a decrease rate of the output of the motor to a decrease rate of the human driving force in accordance with transmission information related to a transmission ratio in a power transmission path between an input rotational shaft of the human-powered vehicle and a wheel of the human-powered vehicle.

Abstract: A human-powered vehicle control device is for a human-powered vehicle. The human-powered vehicle includes a motor that applies a propulsion force to the human-powered vehicle and a shifting device that changes a transmission ratio, which is a ratio of a rotational speed of a wheel of the human-powered vehicle to a rotational speed of a crank of the human-powered vehicle. The human-powered vehicle control device includes an electronic controller that is configured to control the shifting device to change the transmission ratio in accordance with a comparison of a first parameter related to the human-powered vehicle and a predetermined threshold value. In a case where an output of the motor decreases as a vehicle speed of the human-powered vehicle increases, the electronic controller is configured to change the predetermined threshold value.

Abstract: A human-powered vehicle control device includes an electronic controller that controls a transmission device to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle in stages. The controller controls the transmission device so that the transmission device performs a first shifting action that shifts the ratio by only one stage in a case where a shifting condition is satisfied. The transmission device is controlled by the electronic controller so that the transmission device performs a second shifting action that shifts the ratio by two or more stages in a case where the shifting condition is satisfied and a vehicle state of the human-powered vehicle is a predetermined state. The predetermined state includes a state in which a change amount of a parameter related to the vehicle state is a predetermined amount or greater.

Abstract: A drive train comprises a sprocket arrangement and a force-transmission coefficient. The sprocket arrangement includes a plurality of rear sprockets and a plurality of gear ratios respectively corresponding to the plurality of rear sprockets. The plurality of gear ratios includes a largest gear ratio and a smallest gear ratio. The sprocket arrangement includes at least one individual sprocket-space provided between two adjacent rear sprockets among the plurality of rear sprockets. The force-transmission coefficient is obtained by dividing a total gear range quotient by a total number of the at least one individual sprocket-space. The force-transmission coefficient is equal to or larger than 0.97 and is equal to or smaller than 1.36. The total gear range quotient is obtained by dividing the largest gear ratio by the smallest gear ratio.
